A Shared Past for East Africa’s Hunter-Gatherers

Journal Article
Languages that involve "clicks" are relatively rare worldwide but are spoken by several groups in Africa. The Khoisan language family includes a handful of these click languages, spoken by hunter-gatherer groups in southern and eastern Africa. But the grouping of these populations into a single language family has been controversial, with some linguists convinced that a few of the languages are too different to be classified together. A genomic study of 50 African populations, funded in part by The Leakey Foundation, adds some clarity to the relationships between these click-speaking groups and many others.

Evolution and the Mammalian Spine

Journal Article
"Nearly all mammals have the same number of cervical vertebrae, no matter how long or short their necks are--humans, giraffes, mice, whales, and platypuses all have exactly seven cervical vertebrae," said Jeff Spear, a doctoral student from New York University, and part of a team whose Leakey Foundation supported research explored why this characteristic has stayed the same through time and across species.
